The ore dressing technology of chrome ore mainly has Gravity separation process, the chrome ore mining equipment are jig separator, shaking table, spiral classifier, centrifugal concentrator and spiral chute, and sometimes the concentrate will be selected by weak magnetic separator or high intensity magnetic separator to further improve the grade of chromium concentrate and the ratio of chromium iron.
To find the mineral, miners searched for a small piece of ore called “float” and followed it to the deposit, which is often in the shape of a lens-shaped “pod.” They worked small isolated deposits with hand tools. Larger deposits justified the cost of using dynamite, air compressors, jackhammers, and loading shovels/excavators. A few larger mines hired workers and provided room and board. Most
Most modern mining of chromite for steel hardening in the developed world is from massive ore bodies that are amenable to large open-pit or concentrated underground methods, all of which require massive mining and milling methodologies. In South Asia, however, where such large bodies of chromite do not occur, such as those in southern Africa and elsewhere, for example, the small podiform chromite bodies of South Asia have not attracted much attention from multinational mining
However, chromite deposits that are large enough for mining are generally found in: 1) stratiform deposits (large masses of igneous rock such as norite or peridotite that slowly crystallized from subsurface magma); 2) podiform deposits (serpentines and other metamorphic rocks derived from the alteration of norite and peridotite); and, 3) beach sands (derived from the weathering of chromite
The Mining of Chrome in South Africa. This report focuses on the chrome ore mining sector in South Africa. The country holds 72% of global chromite resources, which includes more than 41% of the world’s reserves, and during 2014 the industry produced 15Mt of chromite, exporting 7Mt valued at US$1.1bn. Also produced during 2014 was 3.7Mt of ferrochrome, an alloy of iron and chromium, and 3.6Mt of
degrees open pit mining can go up to a UPD of 23m depending on the market prices of Ferrochrome. •There are some areas in the Middle and South Dyke where the dip is quite steep at 22-24 degrees resulting in high stripping ratios. •In the North Dyke where the dips are above 24 degrees only underground mining is cost effective and practiced.

The chrome raw ore is a flotation tail ore, which is mainly formed in the chromite, and the chromite is the target recovering mineral. The dissociation degree of ferrochromium ore is low, and it has a weak magnetic property. First of all, magnetic separation processing to separate chromite. Besides, the grain size is fine, so there is no need for grinding, the grading result shown in the below.
